PROPELLING AERIALAND MARINE VESSELS.

LPEQIFICATION forming part of LettersPatent No. 302,395, dated July 22,1884.

Application filed April 18, 1884. (No model To all whom it may concern:

Be it known that I, EDUARD GOEHRUNG, a citizen of Germany, and residingat Stuttgart, in the Empire of Germany, have invented new and usefulImprovements in Propelling Aerial, Submarine, and other Vessels,,ofwhich the following is a specification.

This invention relates to apparatus for propelling vessels in water andair. I will first describe it as applied for propelling ships andsubmarine vessels, reference being'had to the accompanying drawings,forming part of this specification.

Figure 1 is a perspective view of the paddle-wheel separately, and Fig.2 a similar view of the wheel in its casing. Fig. 3 is a plan, and Fig.4 an end view of the same when provided with means for adjusting theposition of the casing.

Similar letters of reference indicate corre sponding parts.

The apparatus consists of a cylindrical, spherical, ellipsoidal, orother suitably-shaped strong metallic casing, A,with a sector-shapedopening, 0 h '61) h k, (one-quarterjmore or less, of its perimeter,)wherein rotates a wheel whose shaft G is mounted in bearings in the endsof the casing, and having anysuitable number of equidistant blades, D,of a plain,

'wavy, or bent form, corresponding to the in ternal dimensions and formof the casing A, so as to almost touch the ends and sides of the casing,from which they protrude at the opening, in order to acton the water.This easing A must be fixed to the vessels hull as low as possible belowthe water-line,-the wheelaxle 0 being carried througha stuffing-box inthe vessels side, and connected with the engine for driving it. Thewheel-axle 0 may be placed in a vertical, horizontal, or inclinedposition at both sides, or with vertical or horizontal axles at the backand at the front part of the ship, for reversing. ,The position of thecasing must be such that the water can flow in and out at the front andsides of the opening without hinderance.

The action of the paddle-wheel when com' pletely immersed is as follows:The wheel revolving in the direction of the arrow, Fig. 2, when emergingat t is from the opening in the casing, forces out the water which wasconfined within it against the free water, thus creating a pressurewhich reacts against the paddles and propels the ship. The portion ofwater nearest the axle which has been expelled from the casing is againcarried into the casing, of the opening to fill up the space between theblades, the quantity of water rotating in the casing remaining nearlyalways the same. The direction of the water on leaving the easing iscentrifugal and parallel to the side h h 0 p of the sector shapedopening toward which the blades are moving. If the direction of thepaddle be reversed, the outward pressure of the water will be exerted ina direction parallel to h i h is. The position of the shaft beingvertical, the pressure is in a foreand-aft direction, which can bechanged into a side pressure by altering the direction of rotation, asrepresented in Figs. 3 and 4. The casing A may be so mounted 011 a frameprojecting from the ships side as to be itself ea: palole of partialrotation 011 the wheel-axis, whereby with half a turn of the casing therelative position of the opening can be so altered that the direction ofpropulsion will be reversed without reversing the engine andpaddle-wheel.

For aerial navigation the principle of the propelling apparatus is thesame as above dc scribed, the construction only being modified tocombine the necessary lightness and strength. The speed of fan, however,must be greatly increased to have any effecton the air.

The casing is provided, as shown in Figs. 3 and 4, with hollowjournalsyH, resting in bearings b on a horizontal or vertical frame, R,fixed to the vessel to be propelled, these journals H forming thebearings of the fanshaft 0, so that the casing A can be turned on itsaxis without interfering with the rotation of the fan D. Any suitablemeans of adjustment may be employed. For instance, a spur-.

wheel, a, on one of the journals of the casing A may gear intoa'spunwheel, d, mounted on the frame It, and provided with a crank orother arrangement for turning it, whereby the casingcan be adjustedcircularly in any required position, and locked in. that position by alatch, a, or other suitable arrangement.

more water flowing in at the ends made to act either vertically,horizontally, or

otherwise to vary the angle of the direction of motion at will. c

Having thus described my invention and the manner of employing the same,I clai1n- 1. The combination, with a paddle-wheel for the propulsion ofvessels, of a casing having an opening in its periphery, and embracingand adjustable about the aXis of said wheel, to present the opening invarious directions for the purpose of giving direction to thepropulsion, substantially as herein de scribed.

2. The combination, with a paddle-wheel for propulsion of vessels, andstationary bearings, of a casing embracing said paddle-wheel, and havingan opening in its periphery, and provided with hollow journals which arefitted to said bearings, and which themselves form the bearings for theshaft of the paddlewheel, substantially as herein described.

In testimony whereof I" have signed my name to this specification in thepresence of two subscribing witnesses.
